[systemd-devel] Fwd: Fwd: Excess of StartLimitBurst

Thanks,
Sorry for bad English.

start" and "systemctl restart".

So after my OS is booted up and my service is started - service's start
counter has value 1. So during next 5 minutes it is possible to restart my
service only 2 times, but I can do it 3 times. And question is "Why start
counter is reseted?".

My service is referenced by multi-user.target.wants and some other unit
that executed at shutdown(referenced by Conficts and After). Maybe you
could provide link to the documentation where referencing is described? Or
describe it by yourself?

Thanks
